According to a new study led by Newcastle University, the use of ancient and historical genetic data may help guide conservation efforts.
An international team of conservation experts have revealed how ancient and historical DNA (a / hDNA) is, including: Genetic data Specimens stored in the Natural History Museum can be used to assess population genetic patterns and processes associated with endangered species.
Publish the survey results to the journal Ecology and evolutionary trends, Scientists have shown that a / h DNA can be compared to modern data to inform nature maintenance efforts and policies.Given that many of the ancient and historical samples were collected before the dramatic man-made disasters. biodiversity Loss, these data can be used to show how Genetic diversity Changes in thinking time, especially in relation to changes in the human-related environment.
“Since the first Biodiversity Convention (CBD) in 1993, genetic diversity has been recognized as an important component of biodiversity,” said Dr. Evelyn Jensen, a lecturer in molecular ecology at the Faculty of Natural and Environmental Sciences, University of Newcastle. Although it has been, it is rarely included in conservation policies and regulations. It is ancient and historical by allowing it to solve important conservation issues, such as setting a baseline for genetic diversity within a species. It has not been well appreciated that DNA plays a role in unleashing the temporal aspects of genetic diversity. It estimates effective population size changes and identifies genetic continuity of the population. “
“Our study shows that information from ancient and historical specimens can play a central role in the conservation of biodiversity, and such data to help the country fulfill its CBD obligations. It shows that certain conservation policies that can be incorporated can be emphasized. “
Experts argue that genetic indicators need to be explicitly included in conservation policies in order to enhance the use and impact of a / h DNA studies on biodiversity conservation.To be effective in Conservation activitiesThe role of a / hDNA needs to be clearly communicated to all parties in order to promote its benefits and set reasonable expectations for its potential.
The authors also emphasize that maximum benefits can only be achieved if the conservation community advocates the use of genetic indicators in conservation policies.
Cristiano Vernesi of Fondazione Edmund Mach, Italy, chaired the COST Action G-BiKE and, along with Professor Tom Gilbert of the Globe Institute, University of Copenhagen, held a workshop leading to the results reported in this paper.
“The current molecular tools allow us to consider a myriad of historical and museum collections, such as ancient books waiting to be read. The contents of these books are the evolution of modern organisms. It is directly interesting to understand the trajectory of. In the dimension, we can estimate the direction and intensity of many important aspects such as gene flow, mixing, and allogeneic mating. “
“To maintain the integrity of these books as much as possible, molecular geneticists need to work closely with museum curators and communities. Ultimately, unique information embedded in a / h DNA. Strengthens the strong beliefs of researchers. policy Regulations for biodiversity resource management Maintenance It is necessary to include elements of genetic biodiversity. ”
